Abstract

L'invention concerne un séparateur à cyclone comprenant une entrée destinée à recevoir un gaz et des particules solides, une sortie de gaz située au niveau de son extrémité supérieure, ainsi qu'une partie tubulaire inférieure, cette partie tubulaire inférieure étant munie d'une extrémité inférieure fermée. Un conduit d'extraction de particules sensiblement vertical se prolonge à travers cette extrémité inférieure fermée entre une position située en dessous de l'extrémité inférieure fermée et une position située dans la partie tubulaire et en dessous de l'entrée de réception de gaz et de particules solides. Ledit conduit comprend des ouvertures destinées à l'extraction de particules solides à partir du séparateur à cyclone, ce conduit présentant une zone de section transversale plus petite que celle de la partie tubulaire inférieure, d'où la formation d'un espace entre le conduit et la paroi intérieure de la partie tubulaire inférieure. Un dispositif permettant d'ajouter un milieu de fluidisation primaire est disposé dans la partie inférieure de cet espace.
